Description

CAS: 1121-31-9 | C5H5NOS | 127.161 g/mol

2-Mercaptopyridine N-oxide is used in ratiometric fluorescence imaging of intracellular zinc ions in mammalian cultures. It is used in the radical coupling of benzoyl derivatives of 2-deoxy-D-ribose, with heterocyclic bases to give C-nucleosides. It acts as a ligand and form coordination complexes with palladium chloride. It is a precursor to O-acyl thiohydroxamates. Further, it serves as an antifungal agent. In addition to this, it is used in the preparation of 1-oxa-2-oxo-3-thia-indolizinium chloride by reaction with carbonyl dichloride.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
